Types

type Deps

type Deps struct {
	local.PluginInfraDeps
	Resync  resync.Subscriber
	Watcher datasync.KeyValProtoWatcher /* prefixed for KSR-published K8s state data */
	Contiv  contiv.API                  /* to get the Node IP and all interface names */
	VPP     defaultplugins.API          /* interface indexes && IP addresses */
}

Deps defines dependencies of the service plugin.

type Plugin

type Plugin struct {
	Deps
	// contains filtered or unexported fields
}

Plugin watches configuration of K8s resources (as reflected by KSR into ETCD) for changes in services, endpoints and pods and updates the NAT configuration in the VPP accordingly.

func (*Plugin) AfterInit

func (p *Plugin) AfterInit() error

AfterInit registers to the ResyncOrchestrator. The registration is done in this phase in order to ensure that the resync for this plugin is triggered only after resync of the Contiv plugin has finished.

func (*Plugin) Close

func (p *Plugin) Close() error

Close stops watching of KSR reflected data.

func (*Plugin) Init

func (p *Plugin) Init() error

Init initializes the service plugin and starts watching ETCD for K8s configuration.
